[Solved] How to compare data read from process->readAllStandardOutput() with a string

[SGaist]

Hi,

You should rather use QString. It has all the function needed for what you want

[Swinetha]

even for QString also it's not enter to if condition I am already tested

[SGaist]

Did you simply check/print the content of b1 ? You might have more data than you think.

[Swinetha]

it is also completed.

compared data n read data both are same
even it is not come into if condition

[SGaist]

if the condition fails it means they are not the same. Maybe a control char like \n that you did not see.

hi
what ever I written in the C-Code the same thing is written in GUI even also if() condition is not satisfied.

Can I add anything more to that string.....

[SGaist]

Can you post the exact content of b1 ?
And the code using QString for the comparison ?

[dbzhang800]

please given the result of

qDebug()<<b1.toHex();

and

qDebug()<<QByteArray(text).toHex();

[Swinetha]

sorry for the late reply and thanks for your valuable suggetions I found the solution for this

[SGaist]

Could you share the solution ?

Since you got it working, please update the thread title prepending [solved] so other forum users may know that it is working now :)

[Swinetha]

I am comparing the hexadecimal data directly so it is working.

like if(b1.toHex()==QByteArray(text).toHex())

it is working.
